I was wondering, can i overwrite minecraft's login system to my own mysql database and have there my username, password and skin? I saw this on the old minecraft like alpha 1.something. Can i do it now and how can i do it if i can?

You can do that by replacing the URL's in the Launcher/Client/Server that point to the Minecraft-WebAPI, which is 'api.minecraft.net' (Or is it? IDK) with URL's that point to your own service.

The problem lies in the fact that you have to replace the API-URL in all of the Launcher/Client/Server-code, which also requires that all users that want to play on your Server then have to have that mod (or rather: patch) installed in both Client and Launcher.

I think he's already got an account, this may be useful for a school or something. Setting up 100+ mc accounts are hard, but making a login server for the Windows Login and Minecraft Login could be interesting. (Yes, I know Minecraft in school is kinda a cheesy concept, but don't act like you didn't think about its educational value )

Um... How can you just assume that? We have no idea what he's trying to do. I said to buy the game because even if you manage to "overwrite" the login system, you won't be able to play with other people. There's just no way to trick the login server to think you have an account and play with premium features, such as skins. If there was a way, someone would have done it by now. Minecraft is an extremely popular game, with many kids playing it. Kids that don't have the money or parents credit cards to buy the game. They would absolutely love a way to play Minecraft for free, but its not gonna happen.

Minecraft does not have much educational value in my opinion. There are better programs for anything that Minecraft has to offer educationally.

Well, as an interactive classroom, kinda. If the teacher is tech-savvy, maybe some kind of machine-simulation mods could be implemented. Even electrical engineering with redstone (Maybe, I'm not really sure on how electricity works, I'm still a newb here. )

Nothings impossible, the game is easily modable. (Minecraft Coder Pack has a specially made decompiler )

There is allot of ways to get around it, even offline mode can still connect to LAN (With some modification, I think, I haven't researched that yet). I think Longor means check a different URL for password/username verification. Which is very much possible, with some really good PHP/Java-EE (I think java EE, I seen minecraft's login page using something like that, maybe)

Even electrical engineering with redstone (Maybe, I'm not really sure on how electricity works, I'm still a newb here. )

The only problem with teaching electrical engineering with redstone, is that it follows special rules. It does not behave like it does in the real world. The only value it would have would be mid-level, where you are building gates and latches as a whole, but even then, it is really slow and there are much better programs for that kind of stuff.

Um yes... Its easily modable. I've made mods for it. But again, it is simply not possible to login to the official mojang servers by simply modifying a few lines of code in the launcher. Like I said, if it was possible it would have already happened. Longor meant that you can connect to unnoficial servers. As in you would have to build your own login and skin system.

And yes you can play offline without an account on LAN. Its completely 100% possible, no modifications needed.

It already happened. There are modified clients that make it possible to play in 'offline mode' with a choosable username. The dissappear from the internet often though, it might be because mojang tries to do a thing against them. :9

*cough* MinecraftSP *cough* I used to use one a long time ago. Back when I had no sense of what the game even was. (Swear to god I thought it was a Roblox rip-off, I was 10)

Personally, I think it'd be cool. Figure it out, Longor!

You have to replicate the ENTIRE Account-API 1:1, and it takes a lot of time to get everything right.If you don't get everything right Minecraft will, most of the time, just crash.

I tried it, and it absolutely wasn't worth it. It was actually the worst idea ever.One had to install the 'patch' on every Client that wanted to join my modded Server, and since people are too lazy to do such a thing, I lost all players on my server. ALL of them.
